ABSTRACT: This study was carried out with the aim of investigating the effect of indigenous microorganism (IMO), effective (EM) and mineral fertilizers (NPK) on the yield and nutritional value of groundnut (Arachis hypogaea) in Western Cameroon (Baboutcha-Fongam). The study was conducted during two consecutive years, using a completely randomized block design of 8 treatments repeated three times in each subblock. The sub-plots were enriched with 0, 10, 20 and 40 g corresponding to the treatment of EM and IMO respectively and 3.2 g of NPK in 2019. Subsequently, the best dose that resulted in excellent yields was repeated for the rest of the experiment in 2020. The yield parameters and nutritional value of the two varieties of Arachis hypogaea used in the two consecutive years increase with the contribution of the different doses compared to the control. Overall, a significant increase (p A. hypogaea plants fertilized with EM 20 g (2.15 ± 0.24 and 2.01 ± 0.23 t/ha) and plants fertilized with NPK 3.2 g (2.36 ± 0.65 and 2.04 ± 0.17 t/ha) was not significant. On the other hand, there was a significant difference (P ≤ 0.05) between plants fertilized with IMO 10 g (2.65 ± 0.17 and 2.24 ± 0.2 t/ha) and plants fertilized with EM 20 g and plants fertilized with NPK 3.2 g for both varieties during the two years combined. In addition to being local and therefore adapted to environmental conditions, IMOs could be a promising biological means for improving soil fertility in Cameroon.
